PORTLAND -- As the probe into the disappearance of Kyron Horman enters its eighth week, investigators were focusing their energy on how his step-mother, Terri Moulton Horman, spent a few key hours the morning he vanished.
There were gaps in what she had told investigators she did that day, including a key portion of time that she said she took daughter Kiara for a ride, according to reliable sources, including people who have been interviewed by investigators.
The reliable sources, including people who have been interviewed by investigators, told KGW investigators said that there was probable cause to arrest Terri in connection with Kyron's disappearance, and for soliciting someone to kill her husband but the choice has been for the investigation to continue.
Terri told investigators that she drove Kiara around a series of rural roads for an hour, saying she was trying to calm her down because she didn't feel well. Meanwhile, she told some of her friends that Kiara had an earache.
Investigators have been comparing where she said she was with what they have been able to establish about her movements that day.
There are some things she did that day that were confirmed.
She went to the gym for about 45 minutes that morning and arrived home about 1 p.m. to post pictures from the science fair on her Facebook page.
Surveillance video from stores she said she was at,along with roads she claims to have traveled were being studied to test the veracity of where she said she was for a portion of the morning.
Meanwhile, these sources say that some of Terri's friends have not only been the subject of searches, they have been interviewed by investigators and, in some cases, took polygraphs.
Terri Horman has not been charged with any crime though law enforcement officials have made it clear she is the focus of the investigation.
